Classifiers

Inspects objects/classes to enforce that they respect the zope.interface
they declare to implement/provide. It works with zope.interfaces.

Examples

the unit tests provided with the source package contain a lot of examples
of how to use the package to validate objects and classes.

Discussion

I have written this package mainly out of a specific need for ensuring that
plugins I load into my application would always implement the interfaces they
declared to implement. This is a way to ensure that the application using the
plugin won’t encounter an exception trying to access an attribute that should
be present but is not.

Status

The package is in its early infancy and will not detect an attribute
that is created outside the __init__ method or not present directly on the
class itself. This could be added in the future if there is enough demand.
